Definitions
- a U-shaped groove 12A is formed by bending a tip portion 12c of the other plate member 12 to be adapted to a bending angle of the one plate member 11, that is, approximately 45 degrees with respect to an outer face 12B located on a base end side of the U-shaped groove 12A in this embodiment.
- the U-shaped groove 12A protrudes linearly and obliquely (in the leftward and downward direction in Fig. 3) from the outer face 12B located on the base end side of the other member 12 and constituting one of the wall faces of the duct.
- the joint structure of the duct thus constituted can offer the same function and effects as the fifth embodiment, and since the U-shaped groove 52A is configured such that the width of the larger inner space is greater than that of the opening in cross section, the forming is easy and the geometric moment of inertia can be increased.

Abstract
Description
Thus, a guide rail 63 is formed by a portion on a bottom side of the
Of course, the duct comprising this joint structure is similar to those comprising the joint structure shown in Figs. 17, 18 and can be assembled with a minimum of noise and quickly even by a woman through a simple operation, thereby enabling the duct to be assembled in accordance with the status of work progress.
Thus, because the duct comprising this joint structure can be stored in the form of plate members, they can be stored if the ducts are produced as standard goods on a large scale, they can be delivered with a truck loaded up to the allowable load capacity when delivered to a construction site, thereby increasing delivery efficiency.
Claims (3)
- A joint structure of a duct in which a guide rail extends along a jointing line at which two plate members of the duct are substantially orthogonal to each other in cross section in the vicinity of the jointing line, the joint structure of the duct characterized in that:an end portion of one of the two plate members is bent to form an angle of 90 degrees or more;a U-shaped groove is formed in an tip end portion of the other plate member such that at least an opening portion of the groove is adapted to a bending angle of the one plate member so as to accommodate the bent tip end portion of the one plate member in an end portion of the other plate member;the guide rail is formed by protruding at least a portion on a bottom side of the U-shaped groove of the other plate member from an outer face located on a base end side of a portion where the U-shaped groove is formed and constituting one of the wall faces of the duct.
- The joint structure of a duct according to Claim 1, characterized in that the U-shaped groove extends obliquely and linearly with respect to the outer face located on the base end side of a portion where the U-shaped groove is formed and constituting one of the wall faces of the duct.
- The joint structure of a duct according to Claim 1, characterized in that the U-shaped groove accommodates the bent tip end portion of the one plate member in the opening portion, and the portion on the bottom side of the U-shaped groove protrudes from the outer face located on the base end side of a portion where the U-shaped groove is formed and constituting one of the wall faces of the duct.
